Another update Yesterday I bought myself a used gt bike Got it really cheap £50 it had problems. Rear gears were not working so changed the cable now changes beautifully. Rear tyre had puncture so repaired that. Went for my usual ride and I love the bike. Unfortunately the rear tyre went flat within 1 mile so my dad had to rescue me. It has a front disk brake the brake starts working just by squeezing the brake lever a very small amount however it has very limited stopping power but the rear v brake is very powerful. I will look into why the front brake is not working well thinking maybe new brake pads. The only other problem is the front headset has play and I need to get a new headset or bearing set. But I felt at home on the bike from the first second I got on it was a real pleasure to ride. Front suspension works very well and I feel confident and comfortable on it. I also enjoyed working on it. carerra auction on ebay ends at 8.30 pm so hope I can get reasonable money for it.
